su-3.0.zip (using for rooting using CWM), copied it into the SD card of Flyer.

Notice

If you have HTC Sync installed in Flyer, remove it first.

Step by step

Check the version of HBOOT by: turn off Flyer completely, press and hold 2 buttons Power and Vol Down at the same time to access to Bootloader. At this time, we can unlock Bootloader for 2 HBOOT versions: 1.10.0000 and 1.11.0003.

Reboot the tablet, go to Setting > Application > Development and turn on Debugging mode. Now go to Setting > About Tablet > Tablet Identity, view and write down the serial number of your Flyer.

Using Root Explorer to go to System > Bin and open file build.prop using note editor. Before editing or copying this file, change “Mount R/W” to “Mount R/O”. You can copy this file to PC to edit and copy back to system folder. After copying back, remember to change “Mount R/O” to “Mount R/W”.

Actually, we have checked this phone function for only some countries (including Viet Nam). We are not sure that it can work well for all providers. And please note that to use the phone function, you need to use a headphone (as shown in the last figure). This phone function doesn't work with the built-in microphone.

as far as I have seen the bluetooth headphone is working and paired but indicates no connection... so far...

Actually it would be helpful for me to know which phone-applications, especially the dialer, should be there even without a sim card or.. is ther a way to activate the dialer or even see if it is there?

First, thank you for your comment. To edit the build.prop, in Root Explorer go tin system folder and change "Mount R/W" to "Mount R/O" as in the figure http://i10.photobucket.com/albums/a143/PhamQuang2505/Flyer14.jpg

You can copy this file to PC to edit and copy it back to the system folder.

OK I managed it so far. (AND IT IS REALLY REALLY WOW!!!) It seems that my Flyers OS. (originally 1.07.... -> changed to 1.10... to install revolutionary...) have not had the phone applications on board. Though after installing revolutionary and clockworkmod (http://www.techofweb.com/technology/install-cwm-revolutionary.html)I copied LeeDrOiD-Flyer-V2.2.0.zip (http://forum.xda-developers.com/showthread.php?t=1314334) to the smartcard and installed it via HBOOT-Recovery

..or just how do I copy it to a PC to edit and copy back. I follow the instructions, but when going to root explorer, mounting as RO and clicking on file, it opens the build.prop file and I can see the contents, but no way of editing it????

Hi guys yesterday I was busy instaling the revolutinary and the instalation went on untill the recovery then my power went off and come back again, but it didnt continue , but it does have the Recovery option and when I click on it it shows me a phone with a red triangle. So fro here do i have to download the root explorer and paste it on my SD card

That HTC engineer has no idea of its own product he is developing!!! Flyer has a GSM antenna (using also 3G) and CAN DO PHONE CALLS! You just need to know how to free the phone function (which is by default not visible and closed). This is somehow the same procedure as HTC Shift needed (liberate the SnapView).

If someone finds this to be too complicated: you can choose to install FlyHigh ROM (has already phone function, es explorer and many more). Find it here: http://forum.xda-developers.com/showthread.php?t=1205050&highlight=custom+rom
